A chubby, blunt nosed rat with tufts of long whiskers,
extending from the ear and face. The fur is soft and brown. The molars
have even rows of cusps in a checkerboard pattern of threes both crosswise and
lengthwise.. Otherwise the rat and its skull look like a larger edition of
Chiropodomys. The mammae are 2+2.

Range Description:

The species has a patchy distribution, it has been recorded
from Myanmar and Western Thailand, however, it may be extirpated from these
countries as little natural vegetation remains. An extant population occurs in
Peninsular Malaysia (Musser and Carleton 2005). Specimens of H. longicaudatus
reported from Yunnan by Wang (2003) probably represent H. delacouri.
Countries: Native:
MalaysiaPossibly extinct:
Myanmar;Thailand

Population:

It was formerly recorded as being common in Myanmar and
Thailand ,but all of the natural habitat within the known range has now been
cleared.
Population Trend: Decreasing

Habitat and Ecology:

This species is known only from natural stands of bamboo in
evergreen lowland rainforest. It is a lowland species in the northern part of
its range; it is recorded from around 500 m in Malaysia. The diet of this
species is restricted to various parts of bamboo.
Systems: Terrestrial

Major Threat(s):

This species appears to be associated with natural stands of
bamboo, a habitat of which very little remains within the known range of the
species (D. Lunde and K. Aplin . Remaining stands of this bamboo are
being cut for building materials and other uses. It is possibly extirpated in
Myanmar and Thailand.

Conservation Actions:

It is present in the Cameron Highlands (Malaysia) and is
likely to be present in the Cameron Highlands Wildlife Sanctuary, however, this
needs to be confirmed. There is a need to protect remaining stands of natural
undisturbed bamboo where the species has been recorded, and to conduct
additional surveys to locate any additional remaining populations in habitat
patches.
